That about sums it up as far as I'm concerned. Properly implemented, the buddy/team system is going to be safer than solo diving in most scenarios. But when pressure is on instructors to crank divers out as quickly and cheaply as possible, quality suffers. You can see it in any area that takes time and effort to develop (trim, buoyancy, team awareness, etc). The critique of the system itself seems a bit misdirected here.
Would like to agree, but I'm hesitant. The reason is that I'm an "intermediate" diver but a very experienced back country traveler and everything in the OP makes sense to me if you substitute "hiker" for "diver". The only reason that I can see for having a buddy, from a safety point of view, is redundant air. If you substitute your own secondary air supply aren't you better off in most cases. It's the same in hiking if you carry a PLB you are able to cover almost everything that a companion would provide without the burden of looking out for them.
